CDNTAINER AND PROCESS FOR FORMING THE SAME.

Application filed August 22, 1922. Serial No. 583,539.

To all 10/107721 it may concern:

Be it known that I, VICTOR Manon, a citizen oi the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented a certain new and useful Improvement in Consuch cans as are used by wholesalers to deliver ice-cream to retailers, and used by the latter to contain such products while they are being dispensed; the emptied cans being thereafter returned to the wholesalers to be refilled and again distributed. Of course, such cans must be extremely durable to withstand the rough handling and wear to which they are inevitably subjected and as such containers are retained in iced salt water to preserve their contents, their bodies must permanently liquid tight, and also adapted to be substantially hermetically sealed by closures which may be instantly opened and shut, to facilitate dispensation of their contents. of course, such containers should not have any internal corners or recesses or joints which cannot be readily cleaned of every vestige of their contents, by mechanical means, tor such products readily and rapidly decompose. Moreover, as it is customary to pack such containers in ice and salt water within wooden tubs which are only a few inches larger in diameter than the outside dian'ieters of such containers; 1 find that itis highlydesirable to so construct and arrange such acontainer that its exterior has no enlargement or projection capable of catching; in the ice in which the containers are packed; for it is necessary to remove such containers from their ice packiugs in the vehicles in which they are transported.

for delivery to custmners, and, the pieces of ice in whicl'l they are packed melt to the precise configuration 0f the containers. so as to fit against the same so tightly that it there is the slightest projection at the bottom of the container. it catches in the ice and spills the latter upon the floor of the vehicle when the operator endeavors to remove the container from the tub. Furthermore, an essential step in the manufacture of some containers of the prior art is the filling with solder of all crevices between the bottom and side walls of the containers, in an endeavor to render the surfaces of such containers smoother than they would otherwise be. However, I find that the use of solder in any portion of such a container is highly objectionable, tor the reason that such containers must not only be coated with pure tin, but must be repeatedly retinned, and, in the operations of tinning and retinning such containers, solder, elements of the structures tuse off in the molten tin bath and render the tin unfit for coating, because of the mixture therewith 0t thedit ierent metallic elements of the solder.

Therefore, the object and effect of my invention is to provide containers having the characteristics above contemplated, and particularly to provide methods andmeans for economically forming the joints between the bodi es and the bottoms of such cans as to avoid the disadvantageous projections aforesaid.

lvly invention includes the various novel features of construction, arrangement and procedure hereinafter specified, and particularly such methods and means as to render the exterior line of junction betwen the bottom and side walls oi such containers substantially Hush and continuous with the outer cylindrical circumferences ot the containers, so that it is unnecessary to employ solder in their construction.

In said drawings; Fig. I is an elevation, partly in section, of a container embodying my invention.

Fig. ,XIIisa fragmentary. sectional View ofthe same parts shown in Fig. XI,=but with the joined portions of the bottom plate and said can body pressed inwardly to the r final form shown in I.

.Beferringto, FigI; the can body l has a removable lid closure 2 conveniently provided-with the rigid handle-3; said handle having its opposite ends 4 welded to the top of: said closure 2. Said can body 1 is formed of a .rectangular .primarily flat sheet of metal, convenientlylow carbon steel, which is first bent to the cylindrical blankform 6 .shown in Fig. IV and then united at its abuttingedges 7 conveniently by an electric welding operation, to form a'blank from whichthe body of a can such as shown in Fig. I is formed. A ring 9 of sheet metal, such as is shown in Fig. VI constitutes a blank from which may be formed the flange ring 11. as a. fixture upon-said can body 1. to support saidli'd closure 2, as shown at the right-hand side of Fig. I, and thus substantially hermetically sealthe oint between the bottom end of sad closure and the can when in'the position shown in said figure.

Said flange ring blank 9 is pushed upon said cylindrical can blank 6 until its upper edge is'flush with the top ot-the latter, and the-expanded skirt 12 of said ring blank 9 is then pressed inwardly, against said blank 6, until it is curled to form the toric bead 13 indicated in Fig. I. Although that pressing operation constricts said ring bead 13 upon'said can blank 6; I prefer to subse quently slightly expand said can-blank 6 within said flange ringll. slightly stretching themetalyofybeth said parts, to insure that theyshall thereafter remain in intimate contact. Such expansion is conveniently effected by;thrusting.the mandrel 18 into said blank v6, as indicated in Fig. VII.

vDuring,the aforesaid operation of forming said bead 13.uponthe.top of said can blank .6, any irregularities in the intended circular form of the lower edge i of said blank 6 are corrected by pressing it upon a suitable die; so that said blank 6 will readily fit over the cylindrical portion 19 of the bottom plate 20, as shown in Fig. VII.

Said bottom plate 20 is also formed from primarily fiat sheet metal, by pressing operations which first-cut a circular disk of said metal and then distort it to the cylindrical form shown in Fig. V. It is'to be particularly notedthat the circumferential cdge'2l of said cylindrical portion 15) of said bottom plate 20, which is presented upwardlyin the can against the inner face of the cylindrical wall of the latter. as shown inFigs. I and VII, is substantially sharp so that the interior of the container is smoothly continuousat the junction of said bottom plate 20 with the can body 1.

The primarily cylindrical lxittonredgc of said body 6, and said cylindrical portion 19 of the bottom plate 20 are then inwardly converged to the configuration shown in .Figs. I and IX to form an annular groove 23 around said converged portion of the cap body 6. in a plane atright angles tothe axis of said body, and of less diameter than the mainportion of said body 6. I find it convenient tothus distort said bottom edge of the can body 6 and the bottom plate 20 while spinning them together upon the mandrel 25 under pressure in opposition to said man drel 18, while said mandrels 18 and 25am rotated in coaxial relation, as indicated in -Fig.VII, andby means of a roller 26havingthe annular flange 27, the perimeter of which is substantially the configuration desired for said groove. It may be observed that said mandrel 25 has an annular recess 29 at the region where it is desired to thus distort said can body 6 and bottom plate 20, so that said parts may be inwardly converged while supported in coaxial relation by said mandrel 25.

Thereupon, a chime reinforcing ring 30, preferably of toric configuration, and conveniently formedof a primarily cylindrical wire, is seated in said groove 23 and. thereafter, the bottom plate flange 31. is bent outwardly over said ring 30, conveniently while spinning it upon said mandrel 25 and by means of the cylindrical body portion of said spinning roller 26. It may be observed.

with reference to Fig. X1. that said flange 3.1 o t the bottom plate which is thus bent to cylindrical form exterior to said ring 30 is at first of substantially larger circumferemrc than said can body 6. Hmvever. thefinal step in the process of forming the bottom joint of said container shown in Fig. I. is to press said flange inwardly so as to be substantially continuous with the outer circumference of said body 6, as in Figs. I and XII. I find it convenient to also effect that step in the operation by means of the cylin- Ill) drical portion of said s inning roller 26, while spinning said can ody 6 upon said mandrels 18 and 25, as in Fig. VII.

Although I prefer to thus include a distinct reinforcing element 30 in the chime of the container, as above described; it is to be understood that reinforcing elements of different forms-may be employed, and that joints otherwise constructed in accordance with my invention may be formed without the inclusion of any such reinforcing elements, and yet have the advantage of the substantially smoothly continuous and solderless construction above contemplated.

Therefore, I do not desire to limit myself to the precise details of construction, arrangement and procedure herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
